Arrange the colours into the rainbow order (VIBGYOR mapping) using the given indices. 1. Indigo 2. Red 3. Violet 4. Blue 5. Green 6. Yellow 7. Orange

Introduction / Context:
As with other colour-order questions, the standard is VIBGYOR.

Given Data / Assumptions:

• Index mapping: Violet=3, Indigo=1, Blue=4, Green=5, Yellow=6, Orange=7, Red=2.

Concept / Approach:
Translate VIBGYOR to the given index numbers and list them sequentially.

Step-by-Step Solution:
V → 3I → 1B → 4G → 5Y → 6O → 7R → 2

Verification / Alternative check:
Compare with any textbook diagram of a primary rainbow.

Why Other Options Are Wrong:
Any option altering the VIBGYOR order misplaces bands.

Common Pitfalls:
Swapping red/orange; reversing inner/outer orientation.

Final Answer:
3, 1, 4, 5, 6, 7, 2
